Twelve different video games showing substance use were observed and the duration of times of game play​ (in seconds) are listed below. The design of the study justifies the assumption that the sample can be treated as a simple random sample. Use the sample data to construct a   98 ​% confidence interval estimate of sigma ​, the standard deviation of the duration times of game play. Assume that this sample was obtained from a population with a normal distribution.   4 comma 808 4 comma 998 4 comma 457 4 comma 845 4 comma 900     4 comma 214   4 comma 584 4 comma 798 4 comma 935 4 comma 381 4 comma 464 4 comma 312     LOADING...
